Description

[0002] The front water gutter of the vehicle body is mainly responsible for guiding the water left from the front windshield. At the same time, the front water gutter is also a body structure component that connects the front panel and side panel, and has an important influence on the torsional stiffness and mode of the whole vehicle.

[0003] If the water channel cannot provide sufficient supporting rigidity for the vehicle body, it will easily cause the vertical jump range of the wheel to be too large, resulting in excessive roll angle of the vehicle when cornering at high speed, affecting the handling stability and safety of the entire vehicle.

[0004] In order to improve the rigidity of the front shock absorber seat, the front water trough assembly is usually overlapped with the front shock absorber seat, and even a crossbeam is added under the water trough to connect the shock absorber seat, but the water trough using this method is often more complicated.

[0005] In addition, the structure of the cabin water flow channel in the prior art is usually an integral type or a split type. The integral water flow channel can be split into a front part and a rear part of the water flow channel. The front part of the water flow channel is first welded to the rear part of the water flow channel, and then connected to the front panel by welding.
